I've got gold on this one several times with no problems.
1. Send 2 bears to market
2. when they get back, increase store by one so you can send 2 milks and the cow to market
3. when they get back, get 5 chickens, 1 pig and fully upgrade the PEF and Bun Factory
4. Process pork as soon as it drops, process all 5 eggs at once when you have enough (I send bears to market here, to get them out of my way, you can also sell pig once it drops the pork.
5. while eggs are processing, get 6 flours (in case you miss one!)
6. as soon as pork is done, make the cake factory and completely upgrade.
I make gold between 2:10 and 2:30
